how extend ember.arrayproxy? have tried following: ember.arrayproxy.reopenclass({ flatten: function(){ var r = []; this.foreach(function(el) { r.push.apply(r, ember.isarray(el) ? el.flatten() : [el]); }); return r; } }); but ended writing following solution: // source: https://gist.github.com/mehulkar/3232255 array.prototype.flatten = ember.arrayproxy.prototype.flatten =function() { var r = []; this.foreach(function(el) { r.push.apply(r, ember.isarray(el) ? el.flatten() : [el]); }); return r; }; is there i'm missing in former example? i'm trying stick ember's methodology, prefer not use later. if you're using flatten on instances of arrayproxy you'd want use reopen , , not reopenclass . reopenclass adds method class itself, aka call em.arrayproxy.flatten() http://emberjs.jsbin.com/oqufobeg/1/edit

sorry noobish question, why use string , int , others, if can use object type? i mean use object one; instead of string one; for example, string class declares bunch of methods. if variable declared object , methods declared in object , super classes (none) visible on variable, regardless of type of actual object. you can do string 1 = new string("whatever"); system.out.println(one.length()); but can't do object 1 = new string("whatever"); system.out.println(one.length()); methods , fields resolved on compile time type of variable.
